Aside from his arms dealing enterprises, Wallanooga also had extensive business interests in the Outer Rim slave trade, He was also the Hutt to see for those looking to hire top-quality assassins. He favored and enjoyed working with the Anzati most of all, finding their innate cruelty admirable and almost Hutt-like.

The Sennex pirates sold Aurra Sing to Wallanooga, who had hopes of turning the girl into his own Force-sensitive assassin. He apprenticed her to the Anzati not long after he bought her. Wallanooga was killed by Aurra Sing sometime before 36 BBY when he failed to meet a deal with her.[1]
